To all whom zit may concern.'

Be it knownl that 1 ALPHoNsUs FrnN, a citizen of the United States, residing in the borough of the Bronx, of the city of NewY .Yorin in the State of New York, have in- Men-ted certain new andy useful Improvements in Metal Windows, of which the following is a specitic-ation, reference being had to the accompanying hereof. Y

In hollow metal window frames made of sheet metal, the point of weakness (if any such'there be) in the jambi, both structurally v andas toy weatheptightness, as. such windows have been constructed heretofore, has been at ltheline of the meeting rails of the two sashes in a double-hung window. It has, therefore, been the object of this invention to strengthen the jamb at this point and this purpose is accomplished by the means which will 'be fullyv described hereinafter with reference to theacconipanying drawing in which the inventionr is illustrated and in which: Y n

Figure 1 is a view in sec-,tional elevation Vof so much of Va window as is necessary toy enable the vinvention to beY understood,- a'

portion ofthe bottom sash being shown in operative relation; with the left-hand -ja-Inb anda portion ofthe upper sash being shown in operative relation with the right-hand jamb, the plane of section of the left-hand ljamb and sash being indicated by the brokenV line 1-1 of Figure 2.

Figure 2 is a view in horizontal section on the plane indicated by the broken line 2 2 of Figure l.

Figure 8 is a View in section on the plane indicated by the broken line 3-3 of Figure 1. y

Figure f1 is a face View showing the jamb, the pulley stile and the strengthening block, as seen in elevation from the right-hand in Figure 1.

Figure 5 is a detail view in elevation of the strengthening block.

In the embodiment of the invention illustrated, the j amb is shown as having its main part a formed of sheet metal bent in usual form, as clearly indicated in Figure 2, and a removable, grooved pulley stile, made in two parts b, b1, upper and lower, but otherwise formed as usual, to engage the main body a,

. as indicated in Figure 2. Vertical channels cr grooves al, a?, e3, a* v.are formed, as usual,

` drawing, forming a part..

,in the face ofthe jainb for co-operation with the vertical ledges of Vthe upper and lower sashes `c and 01:. :Heretofore the jamb has been .stiffened only by internal braces., one i ofwhich is shown at UZ inA each jamb, the pulley stile L, b1 being secured to the body of the rjfamb by a screw passed through the pulleystile into the brace. v f y VIn accordance, with'the present invention, the removable, grooved pulley stile is prefj erabl'y Amade inl two parts,'b andfb, upper ,and lower, vand between theinthere is introjduced the hereinafterdescribed block, which in the .Shop is commonly ,called a wedge.. block, by reason of the inclination of por tions of its working face., although ithas no wedging function. This block. e, -to be described more particularly, is secured yby a screw to theheavy vbrace dat the line of..

the meeting' rails-of vt-hevtwo sashes, in reach jamb, and has securedthe-reto, asby screws b2, the corresponding ends ofthe pulley stile Vmembers b and?. The block e sy preferably made as a casting and is for-med on its rearv yface Vwith protecting lugs el which re eive between them the heavy brace gas `clemirly shown in Figure 1. In its outer y or working face it ischanneled, Vvertically shownat. c? infFignre 4,. in ,reg-i.

istration with thechannels Lor grooves @gland a3 in theface of the pulley stile. At its side edges itis rabbeted vertically, as at e3, to re- .ceiveflush ,the edges of the main body of the jamb. On its front or working face it is formed with two oppositely vinclined projections c4 and e5, the one, e4, for co-operation with the lower sash, as shown at the Vleft-hand in Figure 1, and the other, e5, for

co-operation with the upper sash, as shown at the right-hand in Figure 1. The ends of the middle portion ve6 are reduced, as at e7, to receive the corresponding portions of the pulley stile so that they shall be flush with the middle part of the portion e", and the ends of the side members, beyond the blocks or projections c4 and e5, are reduced as at c, c

so as to Vreceive Hush the corresponding right and left-'hand portions of the pulley stile, whereby the channels a2 and a3 in the'pulley stile are continued through the block c 'without shoulders which might interferewith the free movement of the sashes. It will be seen that the bottom member c2 ofthe bottom rail of the-upper sash c overlaps the ledge formed by the projection e5 at each Y thereto.

side and makes contact therewith, while the top member 03 of the upper rail of the lower sash 01 similarly overlaps the ledge formed by the block e4, and makes contact therewith when the sash is closed, whereby, when the sashes are closed, the narrow opening which would otherwise be left for the entrance of cold air, is closed el'ectually. Itwill further be observed that each sash bears only against the end of the ledges of the corresponding blocks c4, c5, and that there is no other contact between any part of either sash` and the j amb, whereby friction between the sash and the amb is avoided, thereby making the movement of the sashes easier and preventing the rubbing o of paint on the exposed faces of the pulley stiles. Itwill also be seen that by the provision of the solid `blocks at the line of the meeting rails of the twosashes,

the securing of the ends of the pulley stile members to such blocks, and the securing of the block through the pulley stile by the screw f to the brace d, the jamb is well supported and stifened at thispoint and is prevented Vfrom yielding or distortion even in in the case of high windows.

- It will be understood that various changes in details of construction and arrangement can be made to suit different conditions of use and that, except as pointed out in the accompanying claims, the invention is not restricted to the particular construction shown and described herein.

I claim as my invention:

l. In a hollow metal window havingi a jamb with a removable, grooved pulley stile, and a heavy brace within the amb, a heavy metal block secured to the brace, channeled in alignment with the grooves in the pulley stile and having the pulley stile secured 2. In a hollow metal window having a j amb with a removable, grooved pulley stile,

. and a heavy brace within the jamb, a heavy metal block secured to the brace, channeled in alignment with the grooves in the pulley stile, 'having the pulley stile secured thereto, and having on its rear face projecting lugs to engage the brace between them.

3. In a hollow metal window having a j amb with a removable, grooved pulley stile, and a heavy brace within the jamb, a heavy metal block secured to the brace, channeled in alignment with the grooves in the pulley stile, having the pulley stile secured thereto, and reduced to receive iiush the co-acting portions of the pulley stile.

at. In a hollow metal window having a j amb with a two-part removable, grooved pulley stile, and a heavy brace within the jamb, a heavy metal block secured to the brace between the two parts of the 'pulley stile, and having said two parts Vsecured thereto. y

5. In a hollow metal window having a jamb and a pulley stile and a'sash having the outside member of its meeting rail eX- tended beyond the sash, a heavy metal block secured to the pulley stile, and having a projecting portion to bear against the sash and to Vform a ledge for contact with the extended portion of the meeting rail.

6. In a hollow metal window having a j amb with a two-part removable, grooved pulley stile, and a heavy brace within the jamb and sashes, and sashes having the outside member of each sash extended beyond the sash, a heavy metal block secured to the brace and having the two parts of the pulley stile secured thereto and having also projecting portions to bear against the sides of the sashes and forming ledges to co-operate' with the projecting portions 0f the meeting rails of the sashes when they are closed.
